于2006年和2008年,向长江口放流了14尾携带弹出式卫星数据回收标志(Pop-up ArchivalTag,PAT)的中华鲟(Acipenser sinensis Gray)幼鱼,其中3龄和9龄中华鲟各6尾和8尾。放流后有9枚标志数据成功上传至ARGOS卫星,标志信息回收率达到64%。初步结果表明,中华鲟幼鱼放流后1个月内即进入海洋生活。进入海洋的中华鲟幼鱼在最长监测期的6个月内正常存活,分布于北起朝鲜西海岸,南至中国福建沿海的经度跨度为4°、纬度跨度为9°的沿海大陆架海域,最大洄游距离达到697km。放流的中华鲟幼鱼呈现随意、迂曲的洄游特征。本实验结果初步证明了中华鲟PAT标志放流取得成功。
In 2006 and 2008, 14 Acipenser sinensis Gray larvae carrying pop-up ArchivalTag (PAT) were released to the Changjiang Estuary, of which 6 Tail and 8 tail. Nine flag data were successfully uploaded to ARGOS satellite after releasing the flow, and the recovery rate of sign information reached 64%. Preliminary results showed that juvenile Chinese sturgeon entered the sea within 1 month after its release. The juvenile Acipenser sinensis survived into the ocean within 6 months of the longest monitoring period. The juvenile Acipenser sinensis survived in the longest monitoring period and distributed in the coastal shelf area off the west coast of North Korea in the north, the longitude span of 4 ° in the coast of Fujian Province of China to the south and the latitude span of 9 ° in the south of China. Migratory distance up to 697km. Released Chinese sturgeon juveniles showed random, tortuous migratory characteristics. The results of this experiment proves that the Chinese sturgeon PAT marks the success of the discharge.
